WHEN COAL WAS KING:  Black Diamond’s Story

Black Diamond is celebrating the 50th anniversary of its Historical Museum this Saturday, June 6th, from 10 am to 3 pm with a ribbon-cutting and new underground coal mine exhibit. The free community event at the 1886 railroad depot (32627 Railroad Avenue) marks a milestone for the museum while honoring the region’s coal mining heritage that shaped south King County’s growth in the late 1800s and early 1900s.
